“…Another key consideration is the occurrence of suitable host plants, which will play an important role in further modulating the potential global distribution and seasonal activity of SLF. While SLF is reported to feed on over 100 host plants (Barringer & Ciafré, 2020), a preferred host plant, Ailanthus altissima (Tree of heaven), is found in all invaded countries and is also present and widespread in Australia (Kowarik & Säumel, 2007). SLF can complete its development and reproduce without access to A. altissima without affecting survival, although development time is increased and the number of egg masses produced is reduced (Uyi et al, 2020).…”

The Spotted Lantern Fly (SLF), Lycorma delicatula (Hemiptera: Fulgoridae), is a sap feeding pest native to southeast Asia that has become a global biosecurity threat following invasions into South Korea, Japan, and the United States in the last two decades. Environmental niche modelling has demonstrated considerable potential for further range expansions, including into Australia and Europe. Further analysis on the potential seasonal life-history and survival of this pest in its invasive range can inform monitoring programs and is a next step in biosecurity preparedness. Here, we incorporated eco-physiological information on the development and survival of SLF life stages across temperature regimes. Using gridded climatic data, we then mapped the developmental sequence of SLF across ranges already occupied in China, South Korea, and the United States, as well as uninvaded ranges in Australia and Europe. The model was able to capture global observations of the seasonal appearance of SLF and highlight regional and seasonal vulnerabilities in regions at risk of invasion. Policy makers can use these results to make science-based biosecurity decisions and target preparedness activities through improved life-history predictions in its invasive range.

“…In prior work by Lee and colleagues [19], the authors reasoned that the improved performance on and preference for A. altissima and V. vinifera is related to high concentrations of sucrose and glucose in A. altissima phloem, and high proportions of sucrose and fructose in V. vinifera phloem. Several authors have also noted that L. delicatula seems to prefer hosts with trunks and branches that do not have thick bark but have high sap turgor pressure, allowing for ingestion of phloem at a greater rate [17,18,20]. The trees used in our study were chosen because they are frequently infested in the field and do not have the thick bark that occurs on oak trees, for example, which are infrequent hosts [29].…”

“…Lycorma delicatula prefers A. altissima in both its native and invasive ranges, though it can utilize over 103 plant species across 33 families [4,17,18]. In North America, feeding by L. delicatula has been observed on 56 plant species, which include native, cultivated, and nonnative species [18]. The rapid spread of this pest is likely facilitated by the prevalence of A. altissima, in addition to other suitable host plant species [18].…”

The rapid spread of this pest is likely facilitated by the prevalence of A. altissima, in addition to other suitable host plant species [18]. Despite the broad host range of L. delicatula, basic information is lacking on its host preferences and relative performance when feeding on common woody ornamentals (but see [19][20]).…”

Despite the broad host range of Lycorma delicatula, the performance of this invasive pest on non-Ailanthus host plant species is difficult to document realistically without using field conditions given this pest’s requirements for vast amounts of phloem. In spring 2020, we examined the performance of L. delicatula with and without access to Ailanthus altissima by tracking development, survival, host tree association and oviposition in large enclosures planted with one each of Juglans nigra, Salix babylonica and Acer saccharinum along with either one A. altissima or one Betula nigra. We reared nymphs with and without access to A. altissima, released them into the corresponding large enclosures as third instars, and monitored them from early July 2020 through November 2020. Insect survival was higher and development faster with access to A. altissima. Third and fourth instar nymphs were most frequently observed on A. altissima when it was present, while adults were equally associated with A. saccharinum and A. altissima. In the absence of A. altissima, nymphs were most frequently found on S. babylonica, while adults were most often on A. saccharinum. Females with access to A. altissima deposited nearly 7-fold more egg masses than those without access to A. altissima. In another experiment, the offspring of parents that had been reared without access to A. altissima showed similar survival and development time from egg to adult as offspring from parents that never had access to A. altissima. These findings suggest that managers need to be aware that even in the absence of A. altissima in the landscape, several hardwood host trees can be utilized by L. delicatula to develop and reproduce.

“…trees from the genus Prunus, and Elaeagnus umbellata (Rosales: Elaeagnaceae). These were all trees or plants that the spotted lanternfly egg masses were seen on during sample collection, many of which have already been reported as host plants for this species [3,31]. The number of bark controls placed into the wheel increased as the dogs became proficient at recognizing their target odor, until six of the other arms (less the one containing the dead egg mass, and one other control, see below) were bark controls.…”

Egg masses as training aids for spotted lanternfly Lycorma delicatula detection dogs

et al. 2021

The spotted lanternfly (Lycorma delicatula) is an invasive species first detected in 2014. The insect feeds on plants causing severe damage in vineyards such as the occurrence of sooty mold fungus that impairs leaf photosynthesis. Currently, there is extensive research on how to track and ultimately prevent the spread of this species. It lays eggs that persist through the winter, while the adults die out, which presents a unique opportunity to enter infested or suspected infested areas to begin quarantine and management of the spread while the species is dormant. Detection dogs may be a tool that can be used to search out the spotted lanternfly egg masses during this overwintering period, however it is not known whether dogs can detect any specific odor from the spotted lanternfly eggs. Moreover, as the eggs are only available during certain times of the year, and hatch based on temperature, finding training aids for the dogs could prove difficult. In this study, we investigated whether three detection dogs could learn the odor from dead spotted lanternfly egg masses and if so, whether that would allow them to recognize live spotted lanternfly egg masses. We found that dogs could be trained to find dead spotted lanternfly egg masses, and could learn to ignore relevant controls, with high levels of sensitivity and specificity (up to 94.6% and 92.8%, respectively). Further, we found that after the training, dogs could find live spotted lanternfly egg masses without additional training and returned to previous levels of sensitivity and specificity within a few sessions. Coded videos of training and testing sessions showed that dogs spent more time at the egg masses than at controls, as expected from training. These results suggest that dead spotted lanternfly egg masses could be a useful training aid for spotted lanternfly detection dogs.
